Let's divide 561541 by 17
The aim is to understand the frequency of 17 in 561541.

Step 1:
The number 17 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 17

Let's proceed to step 2:
17 can be fit into 56 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 51 from 56, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 17

Going ahead to step 3:
17 goes into 51 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 0 after subtracting 51 from 51.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 17

Going ahead to step 4:
17 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 330.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 17

Step 5:
17 goes into 54 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3303.0
Subtracting 51 from 54 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 17

Let's proceed to step 6:
17 can be fit into 31 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 33031.0
Subtract 17 from 31 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 33031.8
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 17 fits into 40 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 33031.82
Subtracting 34 from 40 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 17 fits into 60 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 33031.823
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
17 goes into 90 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 33031.8235
If we take 85 away from 90, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
50 divided by 17 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 33031.82352
If we subtract 34 from 50, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 17, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 33031.823529
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 33031.8235294
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 17 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 33031.82352941
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 33031.82352941 with a remaining 3e-09.
